A Game Master can spend four hours inventing a kingdom, two more drawing its trade routes, and another forty minutes deciding what the local baker calls his cat.
Then Tuesday arrives. The players sit down. Someone asks, “What happens first?”
The baker’s cat is beautifully named. The opening scene is missing.
There’s nothing wrong with loving worldbuilding. The problem comes when preparation grows into a second job and still leaves you unsure what to run. For a weeknight game, you need a different kind of document: something small enough to finish and useful enough to glance at while the table does something you didn’t expect.
Try a two-page Session Compass. One page tells you what can happen. The other helps you respond when it happens differently.
What preparation is actually for
Good prep isn’t a promise that the players will follow your plan. It’s a collection of handles you can grab when the game moves.
Mike Shea’s Sly Flourish approach treats scenes as flexible supports rather than mandatory script beats. Justin Alexander’s Three Clue Rule addresses a different risk: important discoveries shouldn’t depend on one brittle clue or one particular player action. Both ideas point toward a useful principle: prepare situations that can respond to choices, not a route the players must obey.
The Session Compass below is our small, edition-neutral way to apply that principle. It is not a published rules system. Use it with a fantasy roleplaying game you know, adapt it to another setting, or borrow the structure for a freeform story night.
Page one: the playable situation
Start with one sentence that answers the table’s first question.
The opening. What can the characters immediately see, hear, or decide? “The village mill has stopped, and two neighbors are arguing beside the dry waterwheel.” That gives you a place, a problem, and people who care. It doesn’t tell the players what to think.
Underneath, write the situation in three lines:
What changed? The mill’s water channel is empty.
Who wants what? The miller wants the sluice opened; a farmer fears flooding.
What happens if nobody acts? Food processing slows and tempers worsen.
These are your bearings. When the party wanders into a new scene, you can still answer what the world is doing.
Next, write three clues. Not three mandatory tasks. Three ways the players might learn something important.
Clue A: Mud on the sluice lever shows it was moved recently.
Clue B: A ferryman heard a bell from the old crossing after midnight.
Clue C: A repair ledger mentions an abandoned overflow channel.
The clues all point toward a changed water route, but each can appear in more than one place. A clue about mud could surface through examination, conversation, or a villager’s muddy boots. If a player finds a clever fourth way to investigate, use it. You are not protecting the clue list from the players.
Alexander’s Three Clue Rule specifically recommends multiple clues for conclusions needed to move an investigation forward. Our version uses three prepared clues as a compact starting point, not a claim that every mystery can be solved with exactly three.
Then write two pressures. A pressure is a change the world may make, not a punishment for failing to guess the GM’s preferred answer.
Pressure one: Rain begins upriver. The overflow channel may flood by evening.
Pressure two: The miller plans to force the gate open with hired labor.
Either pressure can advance if the players spend time elsewhere. Neither erases a good solution they invent. Pressure gives your setting a pulse without turning it into a railroad.
Finally, leave the ending open. Write two or three plausible outcomes, not a required finale:
The water returns, but someone must repair the bank.
The channel stays closed while the village negotiates a safer route.
The players discover a third option and change the local arrangement.
The actual ending belongs to the table.
Page two: the response kit
Page one describes the situation. Page two helps you keep moving when the players ask questions you didn’t anticipate.
People: Write two or three NPCs, each with a desire and one useful piece of information. The miller wants flour moving again and knows the machinery. The farmer wants her fields protected and saw unfamiliar tracks. The ferryman wants to keep the crossing open and knows the river’s older paths.
Locations: Write three short, flexible sensory details. At the mill: wet grain, a silent wheel, flour dust on boots. At the river: tangled reeds, a cold stone marker, a rope snagged beneath the bridge. At the crossing: a rusted bell, polished steps, a shelter smelling of smoke. These are invitations to explore, not elaborate room descriptions.
Consequences: Prepare three gentle costs that keep the story going. A failed climb may cost time, not cancel the adventure. An awkward negotiation may require a favor. A rushed repair may work but need later maintenance. Follow your game’s actual rules for checks and consequences; don’t overwrite them with this article’s examples.
Rules and names: Note only what you will genuinely forget at the table: a creature’s reference page, a condition you expect to use, a name, or the location of a relevant rule. You do not need to transcribe the entire rulebook into your notebook.
One blank line: “The players surprised me by ______.” Leave it empty. It’s a small reminder that surprise is not a flaw in the plan.

You can copy those headings onto two sheets of paper. If your handwriting is enormous, use three. The point is a finite prep budget, not an argument with your stationery.
The 25-minute Tuesday routine
Minutes 0–4: Read the last session’s notes and write one unresolved question the players seem interested in. Don’t make them chase a hook they’ve already declined.
Minutes 4–8: Draft the opening and the situation. Put an immediate choice in reach. If the group is already mid-scene, start with the next meaningful consequence rather than teleporting them somewhere new.
Minutes 8–14: Write the three clues. Check whether the most important discovery has multiple ways in. If one clue is essential, add alternatives.
Minutes 14–18: Add two pressures. Ask what each interested person would do if the characters didn’t intervene.
Minutes 18–23: Fill page two with names, desires, sensory details and rule references. Spend time on the things you are least comfortable improvising.
Minutes 23–25: Say the opening aloud. If it sounds like a history lecture, cut it until a player can respond to something. Then stop prepping.
Some games demand more mechanical preparation, especially complex combat or unfamiliar systems. Use the remaining time for that rather than pretending every encounter is equally simple. The Compass is a baseline, not a boast about how little work everyone should do.
When the players skip the obvious path
Suppose the party ignores the mill and heads straight to the farmer’s field. You still know what changed, who wants what, and what the river is doing. The farmer can show them the muddy track. The rain can arrive. The ferryman can become relevant later.
You haven’t wasted your prep because your notes describe a situation rather than a sequence of locked doors.
And if they decide the best solution is to gather the village for a meeting? Wonderful. Let the people you prepared express their interests. The story might become a negotiation rather than a dungeon. Your notes still work.
Five prep traps
Writing dialogue instead of motives. A paragraph of perfect speech is brittle. “Wants the bridge repaired before winter” can survive almost any question.
Hiding every useful fact behind a roll. If the adventure requires the players to know the gate was moved, don’t let one unlucky die roll end the session. Use a different cost, clue, or discovery path consistent with your game’s rules.
Treating a clock as a punishment. A rising river creates stakes. It shouldn’t exist only to discipline players who investigate something interesting.
Over-prepping optional branches. One flexible NPC with a motive often helps more than six fully scripted alternatives.
Assuming less prep always means better prep. Some tables love tactical maps, carefully balanced encounters, or intricate mysteries. Prepare what serves your players and your own confidence. The goal is a session you can run, not winning a minimalism contest.
A small experiment before your next game
Take the session you are already planning and write its opening, three clues, two pressures, and flexible ending on one page. Put your NPC desires and rule reminders on the second. Run a finger down the notes and ask: “If the players say no, do I still know what happens?”
If the answer is yes, you have a useful compass.
